This compound displays a favorable photochromism on alternating irradiation with UV/Vis light. Upon addition of Al(III) or Cr(III) to the probe, its color changes from colorless to pink, and its fluorescence is markedly enhanced. The probe displays excellent sensitivity and selectivity for these ions. Another probe (compound 1C) was also prepared and is found to undergo a color change from pea green to pink after binding Al(III) or 30(III). Sensitivities were studied, and competition experiments with various other metal ion revealed that compound 1C possesses good and selective fluorescence response to Al(III) and Cr(III). Figure In this manuscript, a new "turn-on” fluorescent and colormetric probe based on diarylethene and a fluorescent rhodamine unit was synthesized. Upon addition of metal ions, both the open-ring isomer (1O) and the closed-ring isomer (1C) exhibited great sensitivity and selectivity for Al(III) and Cr(III), in which the characteristics of solution such as color, absorption and fluorescence spectra were notably changed. Furthermore, the modulation of the emission intensity of 1 after binding Al(III) or Cr(III) upon alternating irradiation with UV/Vis is reversible. Results indicated that this diarylethene derivative may be used as a potential colorimetric and "turn-on” fluorescent probe for detecting Al(III) or Cr(III).
